C. MAUTNER v JUNCTION B OX Filed Nov. 21-. 1924 position on the conduit, as shown in Fig. 1. The end and top portions of the side sections ll) are cut out so as to engage partly around the conduit, when closed, and hold the box in position without the use of screws or other fastening means and. when opened, permit the removal of the box as a unit, permitting ready ccess to the electrical connee tions. The side sections 10 may be pivoted to the member 6 in any desired manner, but I prefer to use and have shown herein a simple, efiective and inexpensive means for this purpose, each of said end-portions ot the side sections 10 being stamped to form an interior protuberance 11 at each end thereof, said protuberance being adapted to engage in and coact with a complementary depression 12 in the end portion 7 of the base member (3 to form thereby a pivot adapted to permit opening and closing of the side sec tions 10.

The means employed for locking the side sections 10 in position on the base member 6 of the junction box are shown herein as another set of similar protuberances 13 struck up on the inner face of the end portions of the side sections 10 and positioned and adapted for co-action with complementary depressions 14 in the end portions 7 of the base member 6. The resiliency of the members, and especially the resiliency of the ends 7 of the member 6, permits frictional contact of the end portions of the side sections 10 with the end portions 7 of the base member 6 and the springing of the protuberance 13 into the depressions 14, the mem bers 6 and 10 being thus held in this closed position engaging the conduit 3 until the side sections 10 are manipulated to disengage them from said conduit, whereupon the junction box as a whole may be removed therefrom.

It will be obvious that a junction-box of the type described may be made of circular or other than rectangular form, and that instead of the outlet opening 15, adapted to permit a conductor cable 16 to be led therethrough, a socket for a lamp or other fitting may be formed therein.

I have not shown the electrical connections or terminal blocks which are enclosed by the junction-box, as these may be of any of the usual forms utilized for this purpose in the trade, and the present invention has to do only with the novel features of the box proper, as herein described and shown.

It will be apparent that various changes in the details of construction shown and described may be made without departing from the spirit and scope of the invention as defined in the appended claims, and I intend that all matter contained in the preceding description or shown in the accompanying drawings shall be interpreted as illustrative merely of an operative embodiment of my invention, and not in a limiting sense.

What 1 claim is:

1. A junction box for electrical conduits, comprising an open-sided base member, and side sections pivotally attached to said base member closing the open sides of said base member and partially closing the opposite side of said box, engaging the conduit and holding the box in position thereon when ciosed.

2. ii junction box -lor electrical conduits, comprising an open-sided base member having upwardly extending end portions. and Side sections having end portions pivotaliy attached to the said base end portions, said end portions being formed to engage the conduit and hold the box in position thereon when closed.

23. A junction box for electrical conduits, comprising an open-sided base member having upwardly extending end portions, and side sections having end portions, said end portions of the base member and side sections being formed with complementary depressions and protuberances to provide a hinged attachment for said side sections to the base member, said end portions being formed to engage said conduit and hold the box in position thereon when closed.

r. A junction box for electrical conduits, comprising an open-sided base member hav ing upwardly extending end portions, and side sections having end portions, said end portions of the base member and side sections being formed with complementary depressions and protuberances to provide a hinged attachment for said side sections to the base member, said end portions also being provided with another set of complementary protuberances and depressions positioned and arranged to coact and lock said side members in closed position, said end portions being formed to engage said conduit and hold the box in position thereon when closed.

A junction box for electrical conduits, comprising an open-sided base member having upwardly extending resilient end portions, and side sections having resilient end portions, said end portions of the base member and side sections being formed with complementary depressions and protuberances to provide a hinged attachment for said side sections to the base member, said resilient end portions also being provided with another set of complementary protuberances and depressions positioned and arranged to coact to lock said side members in closed position, said end portions being formed to engage said conduit and hold the box in position thereon when closed.

6. A junction box for electrical conduits, comprising an open-sided base member having upwardly extending end portions provided with a shoulder offset therefrom in position to extend over the inner edge of the end of the conduit When the box is in place and adapted to position the box thereon, and side sections having end portions pivotally attached to said base end portions, said end portions bein formed to engage the conduit and hold the box in position thereon when closed.

7. A junction box for electrical conduits, comprising an open sided base member having upwardly extending end portions each formed with an opening in which the conduit is received and the box thereby posi' tioned transversely thereon, the end portions of said base member being also provided With a shoulder ofiset therefrom in said opening in position to extend over the inner edge ofthe ends of the conduit when the box is in place and adapted to position the box thereon longitudinally, and side sections having end portions pivotally attached to said base end portions, said end portions bein formed to engage the conduit and hold the box in position thereon When closed.

Signed at New York, in the county of New York, and State of New York, this 3d day of November, A. D. 1924.

CHARLES MAUTNER.
